Weirdest damn thing, occasionally my network connectivity was being lost. Not the wifi signal, but just the route to the internet. I finally realized today it happens whenever I do a fresh boot (i.e. first time after system boot) of Heroic Games Launcher.
I am running OpenSuse Tumbleweed and using the Heroic Flatpak. Any idea how I would debug what the heck is going on so I can give a bug report to the Flatpak maintainers? I was poking around /var/log but didn’t see anything interesting.
No problem, glad I was able to recognize the symptoms so quickly. It was incredibly frustrating too! Oh, one more thing to do is launch Heroic from terminal so you can see the output. That’s how I knew which game was causing it.
